To all inkom' may concern Be it known that LCI-Lianne lV; DoNHoLT,

a. citizenfoi' the United States, and a resident ori-Ridgewood. in the county of Bergen and State et New ersey,.ha\fe invented certainneW 'and useful Improvements in Pfaclt age-Ties, of which the following is a speciication,

Thisl invention relates to package-ties for connecting and tensioning the ends of t1e-.

cords-for packages or various kinds, and the main object of the invention is 'to provide a. simple, cheap and effective device 'of this4 class'which can bequiclrly attached to and,

detached from the tie-cord and package and maintain allirrn grip onfsaid cord withoutpackage tie-cord; Fig. 'Zis an enlarged edge elerationl of the same looking Jrroin one side of the' device, and` Fig. 3 is an end elevation ol the device on an enlarged scale.

ln carrying the invention into eilect the tie-piece or package-tie 4proper may be .made -with a: body portion of any suitable kind carryin@` one vor more cord-clamps properly constructed as hereafter described. Usually, howeyer, the wliole'tie-piece will be made from sheet material,

diamond-shaped as viewed in plan, but bent or curved so as to be substantially concafvoconvex, as viewed in edge elevation in Fige 2. This curved body portion of tlietie-piece is designated by Q, -At one or both ends thereof i't has a suitable cord-clamp or cordclanips iior gripping a considerable portion of the length of the cord. In the preferred'- l construction shown there are two of these cord-clamps one at each end of the tie-piece and lacing inwardly, but preferably the extreme inner edges ot' the clamps are disposed at a considerable distance apart, as will be seen in Fig. l, in orderto facilitate the placing of the cord inv position in one cordclainp when the device is engaged and the thumb of the user substantially'covers the lother cord clamp.

' The two cord-clamps ofi-the tie-piece are usually" formed in part from the end portions of the body 2 and 'in part from benteup,

element-sl or jawsformed by bending on the lines 3S and 4 which here define the ends of said body portion 2.' TheA lines 3 and 4 also constitute-the meeting lines ofthe jaws 0f .the respectii'e cord-clamps 'formed by bendel ing up the elements just mentioned., 'These bent-np portions are Aindicated at 5 and 6, and constitute the upper jaws of 'the' cord- The package tie is preferablylrelatively wide to providerelatively wide cord-clamps,

'an'cllh'as a' slotof lcon'side-rable length lfor re-l ceiving and ,Qafipping` the' cord to be ti'ed around 'the package. In thev construction illustrated tliis'slot, which is designated by 7 extends approximately half thel width of the.- cordlclalnp (measuredI in .the direction offtliewvidt'l'i of the tie-pice) 'leaving' the upper `and vlower jaws ofyea'ch cord-clamp' directly connected with each other for about half the width of each bord-clamp. The

portion of each cord-clamp' which. is4 not eut in the meeting line of 'it'sjaws 4is a spring-clamp of relatively greatwidth in the construction sli-own :and adapted to eX- ert pressure throughout its width upon the cord at all points in 'the length of such' cord-clampl (measuredin the direction of the length of the tie-piece) after the cord enters the jaws of the 'clamp suiliciently' to be' .in clamping relation therewith. There-v after the clamping pressure upon the cord as it approaches the meeting line of the jaws increases because .the pass between the jaws tapers ,or decreases in widthromtheentrance of each passto the jaws'.v Thus' in the preferred construction a gradually in# creasing pressure is exerted ast-he section, 8, for exampldot the cord()` is forced home, that is, ,in contact with the back wall of the cord-clamp c, atthe meeting line 3 or" the' jaws of said cord-clamp; f The clamping of the cord between th portions of' the cord clamp jawsseparated by the slot v7, for example, is diierent fromV the 'clamping action-between the directly connected parts of the jaws just described.

vThe spring-metal jaws being entirely sepa.-

strongly by the separated jaws at opposite sides of the slot 7, and particularly as it approaches the end wall of said slot, by converging Walls tapering toward the back wall 10, of the slot. Thus, when the end of the cord is passed into the cord-clamp at the unslotted end thereof (theinner edges of the upper jaws 5 and 6 being usually curved upwardly slightly to facilitate the entrance of the cord into the pass) and the section S is forced to the position shown in Figi 1 and lshown the jaws converge somewhat from the uncut toward .the cut side of the cord clamp (this being clearly shown in Fig. 3) and (3) to the wedging action of those portions of the separated or cut jaws which lie in the meeting line of the jaws of the cordclamp. In addition to this, the resistance opposed to the pulling out of the cord after it is once held in place, as shown in Fig. 1, is increased very greatly because of the fact that the cord entering the clamp turns sharply about the wall or corner 11 at approximatelya right angle, and where it leaves the cord clamp at the wall or edge 10 is wedged in lplace also by being turned at a sharp angle. Any pull on-the'cord tending to Withdraw it from the uncut side. of the cord-clamp results in bringing to bear upon the cord a very great amount of friction and the harder the cord is pulled the more tightly it is wedged against the Wall 10 at the narrowest point of the slot 7.

While only one of the cord-clamps is described in detail, it will be understood that the preferred construction is one in which 'two lsimilar but oppositely-disposed cordclamps c and c are so placed as to coact properly Wlth each other. The manner in which the cord is held by the tie-piece or package-tie proper will be clear by referring to F ig. 1, from which it will be seen that the cord is passed once around the package and then at the point of beginning is crossed and -wrapped around the package at a right angle in the usual manner, -after which the fre'eend of the cord, that is, the end not engaged in a cord-clamp at the beginning of the tying operation is passed into theopposite cord-clamp and tightened up, as may be necessary in the manner shown. When the tie is finished the cord outside the tiepiece lies at approximately a right angle to the meeting line of each cord-clamp and the tie-piece itself is outside the crossing point of the cord. A central hole is shown at 12 by means of which the tie-pieces may be assembled on a rod; or whichmay, if desired, be employed as an anchorage point for a knot in those cases where a knot lnay be thought desirable.

lVhat I claim is:

1. A package-tie, comprising a body portion having at one end thereof an inwardly facing cord-clamp slit inwardly froni one side thereof in the meeting line of theaws to form a cord-receiving slot and the yjaws of which cord-clamp converge from opposite sides of the clamp in both directions substantially in said meeting line.

' 2. A package-tie, comprising a body portion having at opposite ends thereof a pair of inwardly facing cord-clamps slit inwardly from opposite sides respectively of the body portion in the meeting lines of their jaws to form cord-receiving slots lying respectively at opposite sides of saidbody portion, the jaws of each cord-clamp converging from opposite sides of the clamp in both directions substantially in the meetingv line of the jaws of said clamp.
